Fig. 8 is an elevational, cross-sectional view oi the mixing tubeillustrating a modified construe ny suitable met andis p ei r o stelined with block tin. The tank may be of any suitable size, and may bemade practically to have a volume of about fifteen gallons. The

tank may be cylindrical, and has a top wall It provided with a centralboss l5 formed with an internally screw-threaded central opening l8.-

portion l9, screwed within the opening IS. The

* head 51 is formed with a central through opening 29 communicating withan internally screw threaded opening 2| at its upper end. The upperportion of the head H is formed with three ,equiangularly spaced,radial, horizontal, screw 'threaded openings 22, 23 and 24 communicatingat their upper ends therewith, and extending to the lower end of thescrew threaded portion 19 of the head.

Fixed within the central opening 2% is an elongated tube 25 to take 01fcharged liquid, preferably made of copper, tinned inside and outside,extending down into the tank I2, and terminating somewhat short of thebottom wall l2a of said tank. The upper end of tube 25 terminates shortof the central screw threaded opening H in the head l'l.

Mounted on tube 25 is a chamber 21 to break up the gas which is fed tosaid chamber from the gas tank H, in the manner hereinafter appearing.The chamber 21 comprises a pair of oppositely'facing-annular heads 28and 29 supporting therebetween a tube 30 made of porous stone orcomposition of the type which serves to break up gas passingtherethrough. Rubber washers 28a and 29a may be interposed between theends of the tube 33 and the heads 28 and 29. The upper head 28 may besoldered or .otherwisefixed to the tube .25 and the lower head 29 may beclamped against the tube by means of a nut 3| screwed onto. the tube 25in any suitable manner.

The head'23 may be formed with a through opening 32, aligned withopening 23a in head l'l,

and of the same size as said head. Fixed within opening 23a is a gastube 34 passing through the opening 32 and projecting substantially halfway into the tube 30. At the lower end of the tube 34 is a rubber tubecheck 35. Tube 34 may likewise be made of copper/tinned inside andutside.

Screwed within the screw threaded opening 23 is a nipple 2311 connectedby piping 3'6 to the gas tank H. The tank l I may be provided with theusual pressure gauge Ha; and interposed in the piping 38 is a hand valve31 and a two way cock 38 which will be described in detail hereinafter.

Upon opening the valve 3! and properly manipulating the valve 88, gas isfed from the tank ll to the piping 38, and through the tube 34 into thechamber 21, for the purpose hereinafter appearing.

Fixed within the opening 24a and extending downwardly therefrom, is ableeder tube 40 likewise preferably made of copper, tinned outside andinside and terminating somewhat above the head 28.

Screwed within the opening 24 is a nipple 24b connected by piping 4| tothe cock 38. The cook 88 is so arranged, as will appear hereinafter,that when the passage of gas from the gas tank to the tube 34 is shutoff, gas from the carbonator tank l2 may pass through the tube 48,piping 4! and cock 38 to a suitable exhaust, to reduce pressure in thecarbonator tank.

The cook 38 comprises a head 45 formed with an internal, central,tapered chamber 48. The head 45 is formed with a quadrangular cut-out41a, and received within the tapered opening 48 is a rotary valve member41 having a transverse through passage 48, and provided with a pin 48disposed within said cut-out. On the rotary valve member 4'! is a usualhandle to rotate the same.

The head 45 has oppositely extending sockets 50 and 5! receiving thepiping 35; and a pair of oppositely extending sockets 52 and 53 disposedat right angles to the sockets 50 and 5| and receiving the pipe 4|, andan exhaust pipe 54, respectively. In one position of the rotary valve41, the iping 36 is open, and when the rotary valve is turned through anangle of 90 degrees, the piping 38 is closed, and the bleeder piping isconnected to the exhaust pipe 54.

Screwed within the opening 22 in the head I1. is a nipple 221) connectedthrough a check valve 88 to a pipe 8! leading to any suitable source ofwater supply. Within the pipe 8| may be interposed a hand valve 62. Thecheck valve 80 permits water to pass to nipple 22b and through opening22a to the interior of the carbonating tank l2. The check valve 88 maycomprise a spring pressed valve stem 65 having a head 68 adapted to seaton the valve seat 61 when the 7 pressure within the tank I2 is above apredetermined pressure. When the cock 38 is turned to bleed the excesspressure from the tank l2, the

pressure is reduced permitting the normal water pressure to open thecheck valve and admit water to the tank l2.

The operation of the apparatus described thus far, is as follows:

Starting with both tanks being empty, faucet until the carbonator isfilled with gas to its maximum pressure. At that time, the faucet 13 isopened to allow the air to escape from the reserve tank I3, and thusallowing it to fill with carbonated water.

To this end, there is screwed into the threaded on the water line.

piping H to the top of tank [3. The carbonated water thus passes fromtube 25, through piping 1| into the tank l3. The carbonated water in thetank I 3 is delivered to the faucet 13 through the medium of the pipe14.

As the carbonated water is drawn oil in dif ferent quantities, thereserve tank and carbonator repeat the above operations automatically.

The hand cook 62 on the water pipe may be closed when it is desired towork on the tank l2. The pressure in the carbonating tank may bemaintained at about 120 pounds pressure, to keep the water back byclosing the check valve The tank is filled up with water, then thecharging of the water takes place, and the carbonated water in the tankis used up. Then, the bleeder is opened to fill up the tank again. Thebleeder bleeds gas pressure from the tank to allow water to come intothe tank l2, because during the bleeding operation the pressure in thetank l2 decreases below the water inlet pressure causing check valve 88to automatically open, letting water into the tank again. The water inthe tank I2 is never allowed to run below the lower end of tube 25 toprevent escape of free CO from tank l2 to tank IS. The CO gas remains insolution in the water in tanks l2 and I3 because said tanks are keptcold.

If tank l2 would run out of water and allowed the reserve to fill with(10* gas, then the first time the faucet 13 was opened after bleedingtank l2 and hence allowing water to fill said tank, the CO gas in tankl3 would be forced to feed gas into the chamber 80.

'tank l3.

In Fig. 8, there is shown a modified construction of chamber forbreaking up the gas. In Fig. 8, the chamber for breaking up the gas,designated by numeral 88 comprises a brass tube 8| tinned inside andoutside. Fixed to the upper and lower ends of the tube 8| are heads 82and 83. The head 83 is formed with a central opening 84 covered by awire mesh tinned screen 85. The head 82 is formed with a central opening8'! to receive a tube 88 terminating somewhat below the head 82, fortaking off the carbonated water.

The head 82 is also provided with a through opening 89 through whichthere passes tube 9!] At the lower end of tube 90 is a rubber checkvalve 9! of usual construction. The inside of tube BI is filled withglass beads 92. The beads are preferably small and are formed withthrough openings.

Gas is thus fed into the chamber 88, and water comes into said chamberto mix with the gas to carbonate the water which passes upwardly throughthe tube 88 and thus passes through the head [1 to the reserve tank.
